I’m a big iced tea drinker, and one annoying little thing I’ve noticed is that if I get freshly-brewed, strong iced tea, it melts all my ice in just a couple of seconds. It’s not hot - which I would understand, with the heat transfer and all - it’s just very, very strong tea.
What causes that? Is it some sort of accelerated osmosis (she asked, pulling a technical term out of her hat)?
I dunno, but I find ice melts quickly in most room temperature drinks. You could make ice cubes out of lemonade or iced tea if the melted ice dilutes it too much.
I always make half as much tea as I want, but double strength; then I fill the pitcher with ice the rest of the way while the tea is still hot and stir til it melts. Voila! Cold tea at the correct strength, to which you can add more ice by the glass without fear.
